Part#: SP690SEN
Part Category: Other Semiconductors

Manufacturer: Exar Corporation

Description: Power Supply Management Circuit, …

The SP690T/S/R, SP802T/S/R, SP804T/S/R and SP805T/S/R devices are a family of
microprocessor (µP) supervisory circuits that integrate a myriad of components involved in
discrete solutions to monitor power-supply and battery-control functions in µP and digital
systems. The series will significantly improve system reliability and operational efficiency
when compared to discrete solutions. The features of the SP690T/S/R, SP802T/S/R,
SP804T/S/R and SP805T/S/R devices include a watchdog timer, a µP reset and backupbattery switchover, and power-failure warning; a complete µP monitoring and watchdog
solution. The series is ideal for 3.0V or 3.3V applications in portable electronics, computers,
controllers, and intelligent instruments and is a solid match for designs where it is critical to
monitor the power supply to the µP and it’s related digital components. Refer to Sipex’s
